Crumb's Dean are you using latch control at every set of traffic lights.

Some people just break gearboxs but you eat them.

JulianD is running around 480-490 bhp and he has a sixspeed with the diffs and he's talking about doing Time Attack 2009, well that was before the present finacial climate.

You may be able to get his phone number off Shaun TDI, just depends what there customer privacy policy is.

Heard that the 6 speeds are good for around 600bhp & ft lbs so you should be OK

Theres a 5 speed PPG straight cut classic gearbox for sale on Scoobynet at the moment http://bbs.scoobynet.com/private-sale-car-...x-complete.html

i know a few of the time attack boys run 6speed so will be ok on 450atw i have a 6 speed coupled to r180 3.9 diff and prop and drive shafts but i know zen had to change something to couple the diff to the prop nothing major

when i had mine done i asked paul@zen what the best option was and he reconed defo a six ifyou can find a good low mileage one but that on its own is a challenge

Dean,

what have you done now?

Go for a six speed jap spec from a forester sti if you can find one!! Best ratios for your power/engine combo.

I wouldnt have a straight cut box/dog box....it will drive you mad after a few weeks....(especially at your age...lol)and they are designed to have rebuilds every so many miles.

The dog box in the rally car was more hassle than it was worth in my opinion!

Give me a call if you like...

Are you having problens with the box Dean?

I know from driving it it's not the most user friendly box, but whether a stock box will take the power/abuse that the car can get, i'm not so sure.

Before the gearbox became a box of neutrals at Silverstone, it had started to jump out of gear every now and again. Just had the gearbox cleaned and re-assembled, but on the way home Gillingham to Maidstone) it jumped out of gear at least ½ dozen times.

I don't have any real information on the gearbox, so sourcing replacement parts is not an option.

I am currently running 381 / 392 at the wheels, but expect it to rise to 430 / 450 ATW when the final bits are done.

Is Julian D running 480 -490 bhp at the wheels?

Would need to check with Shaun, Dean.

Can anyone tell me if this would be suitable? It's for sale at £1750.00

That is a good price Dean if it meets your requirements. Is that from the team that are prepping a group N car?

Hi,

We have a very strong customer privacy policy so i'd be unable to give you his contact information, but i can tell you that Julians 6-speed gearbox is holding up nicely. His rear diff however has had its issues. Since the entire set-up was bought second hand with no guarantee's about the mileage, we could only hope for the best. The first rear diff gave out once we converted it to run on bio-ethanol but judging from the state of it once we pulled it apart, it obviously hadn't had an easy life prior to Julians ownership.

The current diff is holding up well but there are possible plans afoot for both gearbox and diff coolers, depending on testing results in the new year. The gearbox itself has been as good as gold.

[shaun_at_tdi]

deani-age,

I'd say it was suitable but it doesn't look like it comes with the rear diff and the driveshafts. If they're included then it's a steal.

I've been looking at a 6 Speed conversion for a while now for my big power build and you'll be lucky if you can find everything you need for less than £2,500.

As far a gear ratios are concerned, it all depends on the gearbox code. Whatever you go for, be absolutely certain that the gearbox and diff ratios are the same otherwise you're buggered!

What are your current power and torque figures?

Do you think this was a better solution over the semi-helical PPG gear set?

What did it cost you all up?

dean im running low 4s at the mo

i have the same grearbox as you have seen coupled to 3.9 rear diff and use existing drive shafts

cannot remember the exact cost but was around the 2/3 mark for the box and bits

[shaun_at_tdi]

That looks good to me Dean

[shaun_at_tdi]

How much? If you dont mind me asking?

[shaun_at_tdi]

That seems a little steep considering you dont need the clutch and to be honest, even the mileage seems a little high. Lets be honest, no-one buys an Imprezza to potter around in and in my experience, the first 10-15000 miles is when a car gets used the hardest.

I find its the whole 'new car' factor and people tend to smash the hell out of a new car until the novelty wears off. If possible Dean, see if you can obtain the kit with the original gearbox and diff fluids in. I find this gives a better indecation of its wear rather than someone saying 'Yeah, it's alright'.

If you're picking it up in person, try to view the car it all came out of too. It never hurts to see why it was all removed in the first place.

Hope this helps.

[shaun_at_tdi]

I would consider 25,000km to be very low mileage if I were buying an second hand car but when you're looking into buying a specific componant on a fairly specialist vehicle, I'd look to find the lowest mileage possible.

Considering they will fit the gearbox set-up, that kind of money isn't too bad. I was under the impression that you were talking about supply only. Will the clutch be second hand also? or will it be brand new?

Personally, i'd take the opportunity to fit a brand new clutch - something that can handle way more power than you expect to make in the future.

I've just bought the HKS GD Max. It's way more capable than my engine will be, but changing clutches is not only expensive, it's a real pain in the a***. Not such an issue if you get garages and alike to do the work for you but i like to get my hands dirty.

Fit once - fit right and all that.

Shaun

[shaun_at_tdi]

I recommend the GD Max hands down. It's been in Julians car since the very beginning and it hasnt grumbled even once. Thats primarily why I opted to use it. That, and it comes with a flywheel because mines absolutely knackered.

OK, it's expensive but you get exactly what you pay for in this industry

[shaun_at_tdi]

There are 2 kits available.

there is a slightly cheaper kit available called the GD Pro. The main difference is the friction discs(as these are both twin plate clutches), the Max has sprung hubs so it's a bit softer for road use whilst the GD Pro has solid hubs. In my opinion, these are a little too sharp for road use but since your Subaru is primarily a track car....

HKS GD Max £995.00+ vat

HKS GD Pro £935.00+ vat

There is also a single plate clutch available called the HKS LA Clutch.

HKS LA Clutch £895.00+ vat

These kits are for the 6 speed transmission set-up.

If you give me a call, i should be able to sort you out with a discount.

Dean,

The jap spec box will be better suited to your needs.... 5th gear onwards are better ratios...and its got dccd... No brainer for me?
